Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Single values for the category or individual UVCB members are not applicable. Indicative values for the category  for  vapour pressure range are 4 to 240 kPa at 37.8°C

Key value for chemical safety assessment

Additional information

The vapour pressure range of 4 to 240 kPa at 37.8°C was obtained from the CONCAWE (2010) “Compilation of selected physico-chemical properties of petroleum substances” report. The vapour pressure was measured for various low boiling point (gasoline) naphthas according to the EN 13016 -1 method. A range was provided for the vapour pressure because it is not possible to define a single vapour pressure value for a UVCB substance. The quoted range was based on measured values for various category members.
